Showcase Creator Issues

Help! I'm trying to create a slideshow in "swf" format so I can insert it into a website. I can import all the graphics I want, I can save everything but how do I (or can I) save the entire slideshow as an "swf" file? I have Windows 7 and think that maybe the software is not compatible. When attempting to save the swf file, I can readily see the html file, but no swf file. Any advise is greatly appreciated.
Thank you!
